What is the purpose of strain supports for vertical runs of wire?

Strain supports for vertical runs of wire mainly serve the purpose of ensuring proper support. When wires are installed vertically, gravity can exert significant stress on the wires, potentially leading to sagging or strain that could damage the wire over time. Properly supporting the wires not only maintains their alignment and prevents excess tension from causing failure but also contributes to the overall safety and reliability of the electrical system.

Additionally, by providing support, strain supports prevent the wires from becoming loose or detached, thus reducing the risk of short circuits or interruptions in the power supply. This helps to ensure that the electrical system operates effectively and safely over time. Supporting the wires correctly can also help maintain code compliance in electrical installations, as many codes require specific support intervals for wiring.
